Maintaining and caring for the EFOY Fuel Manager
Under normal usage conditions, the EFOY Fuel Manager is maintenance
free. The EFOY Fuel Manager does not contain any parts which you yourself
can maintain or repair. Do not open the EFOY Fuel Manager.
The fuel cartridge can be changed while the device is running. Each fuel
cartridge can only be used once; they cannot be refilled. Do not change the
EFOY fuel cartridge until it is completely empty.
The shelf life of EFOY fuel cartridges is limited. Pay attention to the expiration date on the
back of the EFOY fuel cartridge: MM/YYYY.
If the fuel cartridge is empty, the fuel level LED on the device will light up red (see
S 5.3).
ECTION

Contamination or foreign particles in commercially available methanol
will damage the EFOY fuel cell.
